Hands free dildo play?

Hi all, anyone have any good tips on ways to have hands free dildo play. I have a suction cup dildo which is the obvious choice but have a few nice vibrators which are not suction. Looking for a good position to have it so I can use it with having to use my hands on them...

Ah that would work quite well. Maybe tying it to the leg of my bed so I can get my legs either side would work well! Thanks for that. I can sometimes manage to keep it in position without holding it but the power button is on the end so as soon as I start bouncing it changes settings then switches off!!
